Find the probability for the experiment of tossing a coin three times. The probability of getting exactly two tails

All right, if a single coin is toast and what is the probability off getting a heads be fewer than two tails. Ah, see exactly three tails. Okay, so the simple Spence off tossing coin is head 02 Those are the only true possibilities that you can't have it now. What is the probability off getting its? It's one off, too. And the second question say's. What is the probability of getting fewer than to tells fewer than two tails less than to receive is it was what was you certainly get list on two teeth. Um, tent. Exactly three towels ability off getting t if you just said queen ones with their now high bonuses.

12. Consider the experiment of Tulsa in a fair coin three times. For each coin, the possible outcomes, our heads or tails. We have heads or tails as the possible outcomes and we're going to pulse it three times a list. The equally likely events of the sample space for the three Tulsa's. So there's three Tulsa's so we could result in heads, Heads, Heads, heads, heads, tails, heads, tails, heads, heads, tails, tails, tails, heads, heads, tails, heads, tails, tails, tails heads or all three tails. There's eight possibilities B. What is the probability that all three coins come up heads? So the probability of heads heads heads. Well, this happens one out of the eight times. So the probability of all three heads is 1/8 part B. Also says notice that the complement of the event three heads is at least one tail. Use this information to compute the probability that there will be at least one tail. So if you notice, the only time that three heads occur is the beginning situation, there's only one time that all three heads occur. In every other situation, we have at least one tales, so the probability of at least one tells is 7/8. These two events are compliments.

Now I have a coin that I'm tossing three times. First time, second time and third time. Okay, Now I want to write down all the equally likely events. What can be my outcomes? Well, it is possible that all three of them are hits our first to our heads. And the last one is a tale, or this is a possibility, or this is a possibility, or this is a possibility, or this is a possibility. Are all three of the Martel's okay? These would be eight in numbers. These eight? Yes, they are right. 1234567 And this is the last one. Eat night. 12345678 Okay, Now, in part, we want to find the probability that all three of them are heads. I see that I have eight possible outcomes, and there is only one outcome in which I have all three of them as heads. So what is my probability that all three of them are hits? It is going to be won by it. Okay, Now, if I think about the compliment off all three heads, compliment off. This is going to be that At least one of them is a tale, right? And this is what the question is asking us. They want us to use this information to compute the probability that there will be at least one tail. So what will be that probability? It will be the complement of this, which is going to be one minus one by eight. And this is going to become seven by it. So this is my probability that I have at least one tail. And even if you count here, you will find that there are seven cases out off eight in which I have at least one tail. 123456 And this last 177 out of it. This is what we've got here.

Okay, so we are tossing three coins. We want to find out the following probabilities firstly. We want to find the same space. So the simple spaces either had a head or ahead, ahead head and the tail a head, tail, head and then a tail and the head and the head. Oh you can toss three tails or tail or tail in the head or tell a head in the tail or head tail tail. So basically there are eight. There are eight outcomes. Okay then be mm sees find exactly one hand. So one probability or find exactly one hand. So one head, you will find it by looking anyway after the T. T. T. So we have got 123 cases. So that will be three out of the sample space which is eight. Then see uh It must two tails or probability that the tails are less or equal to tomb it most is less or equal to. So two tails or or less. It means what you don't want Our three hands only. Anything else will meet the condition. So we have got seven cases out of possible eight. Uh Then we go to d at least one had probability that we have at least one had means one head or more. So it's greater than 8.1. So one herd means what we only don't want zero head which is T T T. So anything else is fine. So this will be serving over eight And then the last one says Exactly two tails probability but we have exactly two tails. So two tails you get them after defeating. So one 23 cases. There are three cases out of a possible aid. Yeah.
